Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Objective To analyze esophageal cancer burden trends in China from 1990 to 2021, further project the burden from 2022 to 2050. Methods The time trends of standardized incidence, standardized mortality, and standardized disability-adjusted life years (DALYs) rate of esophageal cancer in China from 1990 to 2021 using data from the Global Burden of Disease 2021 were analyzed using the estimated annual percentage change (EAPC). The disease burden of esophageal cancer in China from 2022 to 2050 was predicted using the Bayesian age–period–cohort model combined with sensitivity analysis and model calibration. Results In China, the ASIR of esophageal cancer increased from 17.637 per 10⁵ in 1990 to 22.548 per 10⁵ in 2021 (EAPC=0.55, 95%CI: 0.38–0.71). The ASMR rose from 17.920 per 10⁵ in 1990 to 20.836 per 10⁵ in 2021 (EAPC=0.21, 95%CI: 0.02–0.39). The age-standardized DALYs decreased from 497.437 per 10⁵ in 1990 to 484.884 per 10⁵ in 2021 (EAPC=−0.39, 95%CI: from −0.59 to −0.2). Among individuals aged 45 years and above, the proportion of esophageal cancer cases increased from 93.32% in 1990 to 97.56% in 2021, and the proportion of deaths in this age group rose from 90.44% in 1990 to 98.22% in 2021. For individuals aged 40 years and above, the proportion of DALYs attributed to esophageal cancer increased from 95.29% in 1990 to 98.29% in 2021. Among people aged 20 years and above, the incidence rate of esophageal cancer showed a downward trend in all age groups. In particular, the 35–39 year age group exhibited the most significant decline (EAPC=−3.74, 95%CI: from −4.22 to −3.25). Among individuals aged 20 years and above, the 70+ year age group had the smallest decrease in ASMR and age-standardized DALYs. By 2050, the standardized prevalence, standardized incidence, standardized mortality, and standardized DALY rate of esophageal cancer in China were predicted to decrease to 25.1/10⁵, 6.4/10⁵, 14.2/10⁵, and 12.0/10⁵, respectively. Conclusion From 1990 to 2021, the ASIR and ASMR of esophageal cancer in China showed an upward trend, whereas the age-standardized DALY rate exhibited a slow downward trend. Although the incidence of esophageal cancer showed a downward trend across all the age groups from 20 years and above, the overall standardized rate exhibited an upward trend due to factors such as population aging. By 2050, the burden of esophageal cancer in China, including prevalence, incidence, mortality, and DALYs, will decline. The population aged 45 years and above is the core group affected by esophageal cancer and should be prioritized for prevention and control.

Objective To investigate the impact of ultrasound intervention combined with tripterygium for ovarian endometriosis cyst(OEC)on the ovarian function of patients.Methods The clinical data of 107 patients with clinically-conformed OEC,who received treatment at the Yuyao Municipal People's Hospital of China from December 2022 to June 2024,were retrospectively analyzed.According to different treatment methods,the patients were divided into control group(n=53)and observation group(n=54).The patients of control group were treated with laparoscopic cystectomy,while the patients of observation group were treated with ultrasound intervention combined with tripterygium therapy.The uterine artery blood flow parameters,sex hormone levels,tumor marker levels,ovarian reserve function were compared between the two groups.Results After treatment,uterine artery blood flow parameters were decreased in both groups,the levels of uterine artery blood flow parameters in the observation group were significantly lower than those in the control group(P＜0.05);the levels of sex hormones were elevated in both groups,the levels of sex hormones in the observation group were obviously higher than those in the control group(P＜0.05).After treatment,the tumor-related indicators generally decreased,especially in the observation group receiving combination therapy,the levels of tumor-related indicators were significantly lower than those in the control group receiving simple surgical treatment(P＜0.05),indicating that the therapeutic effect of the observation group was better than that of the control group.After treatment,the ovarian reserve function of both groups were increased when compared with their preoperative values,and the ovarian reserve function of the observation group was higher than that of the control group(P＜0.05).Conclusion In treating OEC patients,ultrasound intervention combined with tripterygium can regulate the levels of sex hormones,reduce tumor marker levels,improve local uterine blood flow status,and protect ovarian reserve function.This therapy is worth promoting and applying in clinical practice.

Peritoneal metastasis of colorectal cancer is the second most common metastatic pattern after liver metastasis, clinically common and associated with a poor prognosis. Refractory subtypes such as mucinous adenocarcinoma, signet-ring cell carcinoma, and BRAF V600E-mutated colorectal cancers account for a relatively high proportion in peritoneal metastasis. While previous diagnosis and treatment faced significant challenges, recent advances in new technologies and evolving therapeutic concepts have achieved progress in management. Many patients with colorectal cancer peritoneal metastasis have obtained favorable treatment outcomes, though numerous challenges persist. This article provides an in-depth analysis of current status and advancements in the diagnosis and treatment of colorectal cancer peritoneal metastasis, examines existing clinical difficulties and unresolved issues, and explores the application of advanced technologies in clinical practice. Through promoting individualized, precise, and standardized treatment concepts, we aim to enhance survival benefits for more patients.

Probiotics are natural systems bridging synthetic biology, physical biotechnology, and immunology, initiating innate and adaptive anti-tumor immune activity. We previously constructed an all-in-one engineered food-grade probiotic Lactococcus lactis (FOLactis) which could boost the crosstalk among different immune cells such as dendritic cells (DCs), natural killer cells, and T cells. Herein, considering the limited clinical efficacy of naked personalized neoantigen peptide vaccines, we decorate FOLactis with tumor antigens by employing a Plug-and-Display system comprising membrane-inserted peptides. Intranodal injection of FOLactis coated with neoantigen peptides (Ag-FOLactis) induces robust DCs presentation and neoantigen-specific cellular immunity. Notably, Ag-FOLactis not only triggers a 45-fold rise in the quantity of locally reactive neoantigen-specific T cells but also induces epitope spreading in both subcutaneous and metastatic tumor-bearing models, leading to potent inhibition of tumor growth. These findings imply that Ag-FOLactis represents a powerful platform to rapidly and easily display antigens, facilitating the development of a bio-activated platform for personalized therapy.

Objective:To investigate the effectiveness of the Rain Classroom teaching model in the Functional Experiment Science.Methods:A total of 61 clinical medicine students from grade 2021 at a medical college were enrolled and divided into the control group(n=30)who received traditional experimental teaching,and the experimental group(n=31)who was taught using the Rain Classroom teaching model.Ultimately,the outcomes compared between the two groups included scores of experimental assignments,satisfaction with the teaching model,and the experimental group's supporting rate for the Rain Classroom teaching mode.Results:The experimental score in the experimental group was significantly higher than that in the control group(P＜0.05).Additionally,58.06%(18/31)of the experimental group supported the Rain Classroom model.Among the experimental group,77.42%(24/31)and 70.97%(22/31)of the students believed that the Rain Classroom teaching mode could enhance the awareness of autonomous learning and the mastery of key and difficult knowledge.Conclusion:Through the Rain Classroom teaching mode,students'experimental grades have been improved,and it also plays a certain role in promoting the enhancement of their self-study ability.

Purpose To investigate the differential expression of proteins secreted by diffuse-type gastric cancer-associated fibroblasts(DGC-CAFs)and intestinal-type gastric cancer-associated fibroblasts(IGC-CAFs)according to Lauren classification of gastric cancer.Methods Fresh surgery samples were acquired to extract primary cancer-asso-ciated fibroblasts(CAFs)to obtain the conditional medium,including three cases of diffuse-type gastric cancer(DGC)and three cases of intestinal-type gastric cancer(IGC).Then high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)was used to detect the differences in secreted factors between DGC-CAFs and IGC-CAFs.Additionally,a total of 1 174 cases were collected from the GEO and TCGA databases,and the distribution of stromal cells was assessed via ESTIMATE to derive stromal scores for both DGC and GC.Furthermore,Kaplan-Meier survival analysis was performed to evaluate the relationship between high stromal scores,elevated CAFs proportions,and patient prognosis.Subsequently,GO enrichment analysis was performed to investigate associated genes and their bi-ological functions.Results HPLC-MS/MS analysis showed that only 10 proteins were identified to be expressed in both DGC-CAFs and IGC-CAFs,namely SPARC,COL6A1,COL1A2,COL1A1,COL3A1,FN1,DCN,ACTG1,TIMP1 and SHROOM3.There were 8 proteins expressed higher in DGC-CAFs than IGC-CAFs in all cases with ratio＞2,namely COL3A1(5.28),COL1A2(3.98),DCN(3.71),TIMP1(3.40),COL6A1(3.35),ACTG1(3.13),COL1A1(2.84)and SHROOM3(2.50).Two other proteins,TUBB and BASP1,were identified in all three cases of DGC-CAFs.The former was only identified in one case of IGC-CAFs,while the latter was not identified in all three cases of IGC-CAFs.The results of bioinformatics analysis showed that the stromal score of DGC was higher than IGC,which correlated with poor prognosis.Analysis of cell components revealed that the related genes were more enriched in ECM,collagen-containing extracellular matrix and cell-cell junction.Also,the biological process and molecular function was based on the components,which was consistent with HPLC-MS/MS analysis results.Conclusion There are differ-ences in secreted proteins of DGC-CAFs and IGC-CAFs,both on the types and the content.The differential proteins are mostly enriched in ECM-related signaling pathways.Presumably,the high content of CAFs in the stroma affects the prognosis of gastric cancer patients by influencing the gene expression and the function of receptor pathway of ECM.
